Pseudocholinesterase in the serum of allergic subjects

Abstract

There are no differences, between human normal and allergic sera, in the total activity of naphthylacetate-hydrolysing enzymes. No abnormal dibucaine-inhibited isoenzymes were detected. The Michaelis constants and the activation energies of serum pseudocholinesterases in the sera of patients with atopic disease, urticaria, or extrinsic allergic alveolitis were within the normal range.
